There is no fixed version for RHEL:9 kernel-64k-debug-modules-partner.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-modules-partner package and not the kernel-64k-debug-modules-partner package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

s390/ctcm: Fix double-kfree

The function 'mpc_rcvd_sweep_req(mpcginfo)' is called conditionally from function 'ctcmpc_unpack_skb'. It frees passed mpcginfo. After that a call to function 'kfree' in function 'ctcmpc_unpack_skb' frees it again.

Remove 'kfree' call in function 'mpc_rcvd_sweep_req(mpcginfo)'.

Bug detected by the clang static analyzer.
